As utilizing above-mentioned project, due to the change of the shape of the member bar composed the side stay-bar component in the present invention, such like using scissors -shaped member bar instead of the conventional straight, the composed top edge of the tent frame appears to flat line without waved line as said conventional tent frame, so that the tent has four flat top edges after covering awning over the frame, it not only shares the weight of roof over the line-shaped side stay-bar components homogeneously efficiently avoiding point-loading happened, but also avoids stockpiling rain water, and further to avoid part portion damage of the tent roof and roof collapsing happened.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a scheme of the prior art.

FIG. 2 is a scheme of the present invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 2, a tent frame provided by the present invention is typically comprised of poles 1, side stay-bar components 2 and roof brace components 3, said roof brace 3 component is hinged on the tip end of the pole 1 with one end, and another end is hinged to others, said side stay-bar component 2 is hinged on two adjacent poles 1.

Wherein, said side stay-bar component 2 is constructed at least of two scissors-shaped member bars 21 crossly hinged together, the number of the scissors-shaped member bars 2 depends on the size of the tent, but the number always is even. The preferred embodiment of the present invention is shown in FIG. 6, in which the side stay-bar component 2 is constructed of six scissors-shaped member bars 21 to compose three pairs of inter-pivoted pairs of cross-hinged scissors-shaped member bars 21 to form flat top edge of roof, in which said two adjacent pairs of cross-hinged scissors-shaped member bars 21 are connected by crossing rare end to coordinated front end respectively in pivot junction. In the same way, the others even numbers of the scissors-shaped member bars are arranged as same as the same, not repeat in here.

The present invention changes the shape of the member bar composed the side stay-bar component 2 in the design, such like using scissors-shaped member bar 21 instead of the conventional straight, the composed top edge of the tent frame appears to flat line without waved line as said conventional tent frame, so that the tent has four flat top edges after covering awning over the frame, it not only shares the weight of roof over the line-shaped side stay-bar components 2 homogeneously efficiently avoiding point-loading happened, but also avoids stockpiling rain water, and further to avoid part portion damage of the tent roof and roof collapsing happened.

The structure of the side stay-bar component 2 in the present invention also can be used in the roof brace component 3; the similar structure is not shown in drawings. In this case, the roof brace component 3 is constructed at least of two scissors-shaped member bars crossly hinged together, a tent frame including more than eight cross-hinged scissors-shaped member bars is for example, the number of the scissors-shaped member bars depends on the size of the tent, in which two adjacent pairs of the cross-hinged scissors-shaped member bars can be serially connected in pin junction with the coordinated ends, in the top center of the tent frame the four double-ends coming from the four corners are hinged together whatever four upper ends or low ends, by changing the shape of the member bar of the roof brace component 3, the present invention takes collapsible scissors-shaped member bar instead of the conventional straight member bar to form a level roof constructed by horizontal-hinged roof brace components, therefore the level tent roof and said four flat edges construct a quadratic tent frame, and after covering awning over it a quadratic tent with a plain roof is built on different from the conventional tent with a church roof, this structure can be used in composing large size series tent with more beautiful and functional.
